PLASMA-TREATED IRON PARTICLES WITH IMPROVED OXIDATION AND CORROSION STABILITY
Original language description
The corrosion and oxidation of iron represent an obstacle for their wider commercial usage, for example in magnetorheological suspensions. To overcome these limitations, modification of surface chemical composition of particles seems to be efficient way.Thus, Teflon-like surface layer onto iron particles has been fabricated in plasma discharge using octafluorocyclobutane as a carrier gas with an admixture of argon. RF plasma reactor with rotating rectangular parallelepiped glass reaction chamber fixedbetween the two discharge electrodes arrangement was used to achieve a uniform surface modification of particles. The influence of various treatment times (60 ? 600 s) and plasma powers (33 ? 100 W) on surface layer composition and consequently oxidationand corrosion stability were tested. In order to determine the surface chemical changes after the plasma treatments, high-resolution X-ray photoelectron spectroscopy measurements were used. On the other hand, the morphology changes were
